GenericMulti-Function Wrench Spanner Combo for Removal and Installation, Black

I've only used this wrench's castle nut and muzzle device tools so far, but it's worked on both. The other reviews were people said it doesn't work with their gun, I don't know what they're talking about. Maybe one of the other parts of this multitool won't fit something on my rifle, but I have yet to come across it.

I figured this was going to be worthless but I am impressed at how well it works. The tool works great for many tasks on my AR. I expected it be lightweight and cheap since it is far below the price of what you usually get them for in the store. Instead it is heavy duty and sturdy as all heck. The finish seems to be holding up too. The fit and finish of the piece is where they did cheap out as it is no where as clean as what you would normally get. Still, it isn't a bad item at all and works great.

I bought this tool specifically for my muzzle device and it doesn't fit around the flash hider at all. Waited all this time for nothing, it doesn't fit the flash hider nor does it fit the comp I was planning to put on. Useless!

This multi-function spanner works great for the AR platform and has just about every feature you would need to work on your equipment. It has a good finish and is well made so it should last for a long time. This is now part of my kit and will make maintaining my 'tools' a lot easier. This is a great spanner wrench for the price and definitely something you'll want in your kit too!

This AR tool is super heavy. The casting is not great. I can’t see carrying this thing in my shooting bag. It’s okay to keep at the work bench. Or as a spare. And it’s not cheap either.

This thing is your basic standard multi wrench for working on an AR. Everything you could want an AR wrench. The main problem with some of these is that they are so cheaply made and coded that the coatings add thickness to the precision notches and they no longer fit what they are supposed to fit. That is not a problem here this thing is fairly well-made and even though the anticorrosion coating is a bit on the rough side it fits all of the appropriate parts. If you’re looking for one tool to do it all this is going to work. It’s a good 30% cheaper than buying it anywhere else I’ve seen them.

I recently had need for one of these tools as I built a new AR, I plan to build another so having this tool will come in handy, if you do any of your own AR service this is a must have tool.

Will not fit on mussle break or the butt stock retention ring. Worthless hunk of metal.
